Emotional Design Flashcards
Tractinsky ATM Experiment
Perceptions of system usability were affected by the interface’s aesthetics and not by the actual usability of the system.
Emotions and Cognition
Emotions play a critical role in daily lives, helping assess situations as good/bad, safe/unsafe. Basic survival property of human mind.
Negative Emotions Affect Decision Making
Stress can cause faster, more intuitive strategies for decisions. Narrows attention. Discourages creative thinking. Encourages response perseveration.
Being Happy
Broadens thought processes and facilitates creative thinking.
Positive Emotions Affect Decision Making
When relaxed and happy, thought processes expand, become more creative and more imaginative. Better at brainstorming, better at examining multiple alternatives.
Role of Aesthetics in Product Design
Attractive things make people feel good, which in turn makes them think more creatively.
Repeat Same Operation Over Again
Especially likely for those who are anxious or tense.
Attractive Things Easier to Use
Happy people are more effective in finding alternative solutions and are more tolerant of minor difficulties.
Affect, Emotion, Cognition
Evolved to interact with and complement one another.
1) Cognition- interprets the world, leading to increased understanding and knowledge
2) Affect- includes emotion, is a system of judgment, good/bad, safe/dangerous
Affective System
Controls muscles of the body and, through chemical neurotransmitters, changes how the brain functions.
Three Levels of Processing
We are conscious of our role in the world and we can reflect upon past experiences.
1) Visceral
2) Behavioral
3) Reflective
Visceral Level
Automatic, prewired layer. Fast reactions about good and bad. Rapid judgments. Alerts behavioral and emotional responses. Lowest layer.
Behavioral Level
Part that contains the brain processes that control everyday behavior. Site of most human behavior. Middle layer. Can interact with both visceral and reflective.
Reflective Level
Contemplative part of the brain. Cognitive, intellectual level. No direct access to sensory input or control of behavior. Watches over, reflects. Highest layer.
Attractive System
Visually, auditorily, or tactilely appealing will affect HOW you use the system.
